Should Brokers Depend on Only One Liquidity Provider?
If a broker uses only one liquidity provider, he reduces the maintenance costs of his system but may take on

In this article, Jonathan Brewer describes the advantages of a Prime of Prime solution as the sole liquidity provider. I am not a supporter of using this business model, as I think that only in conditions of healthy competition can we find optimal solutions both in business and in life. I think that a business model with one liquidity provider is suitable only for a limited group of Forex brokers. I’ll explain my position below…
First of all, I would like to distinguish two main groups of retail brokers:
1. Brokers who largely operate as market makers (MM), i.e. act as a counterparty for client transactions.
2. Brokers who provide access to interbank liquidity, that is, act as an intermediary for client positions.
Of course, nowadays the line between the two is blurred. Despite the fact that a lot of retail forex brokers have in their product line both MM and ECN/STP accounts, they still continue to adhere to either the first or the second model of doing business.
Then I propose to define the goals or tasks that force both groups to seek a liquidity provider (LP).
For the first group, it is primarily the need to hedge some portion of the client’s positions and then the possibility of expanding the product line through ECN/STP accounts. For the second group it is getting a reliable supplier with consistently tight spreads, executable prices and low commissions.
the connection costs and maintenance fees of multiple providers in your system are a small price to pay for avoiding being bound hand and foot to a single LP
It is clear that the objectives of these groups differ from each other. The needs of the first group can be satisfied by almost any supplier, those of the second group cannot. We can conclude from this that the second group will be more sensitive to changes in the conditions of the liquidity provider.
Of course there are many ‘signs of compliance’ when choosing a liquidity provider, but for the purposes of this article we are only interested in tasks which forex brokers try to solve when selecting an LР.
Thus we will not list here all the criteria that liquidity providers are required to meet.

So let’s imagine some situations that can happen whilst working with an LP:
1. Your supplier informs you that due to the low volumes that you send him, he can’t hold your commission payments at this level and is forced to raise it.
- The LP notifies you that some banks refuse to work with him because of the large number of small positions which you send him and as a result liquidity will be thinner and spreads correspondingly wider.
- The LP stops pricing on an instrument from your list because of low volumes or other reasons.
- You have a dispute with the LP after a technical failure on the provider’s side.
These are real issues faced by brokers on a daily basis. All these situations will put your business in an undesirable position. You will be forced to accept all these risks and as a result, carry the reputational and material costs. I should add that the process of connecting a new liquidity provider takes on average 2-3 months. It will not allow you to find an alternative solution quickly.
Thus, if you are using a model with one liquidity provider, you reduce the maintenance costs of your system but you may become completely dependent on the LP.
Conclusion
If the broker works as a market maker and needs an LP to hedge only part of a client’s positions, the business model of one LP is completely justified: if the LP changes the terms, or has a short-term technological issue, it will not threaten your business.
Conversely, brokers who provide their customers with access to interbank liquidity via an ECN/STP account cannot use only one LP. All the connection costs and maintenance fees of multiple providers in your system are a small price to pay for avoiding being bound hand and foot to a single LP, and having to take all of its risk.
Sergey, Thank you for your very erudite retort to my article. It is regrettably however very clear that you did not in fact understand my original article. My article very clearly states that re-aggregating feeds that are already ECN feeds comprising a number of Primary LP connections is not a sensible business model for the reasons that I mentioned. Going back to your numerated points, every single one of them are reasons why it is sensible to trade with an LP that provides a price feed that is an aggregation of primary market LPs, which is exactly the business model… Read more »
Jonathan, Sorry for the delay. I just didn’t expect you left a comment here. I understood your idea very well. However, I remain unconvinced. The business model with one supplier is very vulnerable, no matter what conditions a single provider offers you. As another example, I can cite here a case which occurred last Friday, when, the system of our LP failed during the rollover procedure. As a result, we had not received prices from this vendor within 24 hours. I think that the failure of the system for such a long period had a negative effect on our reputation… Read more »
Sergey, You STILL have not understood my article, nor have you responded to any of the relevant aspects of it. I have not suggested that a client should use a single liquidity source. I am suggesting that they should use an aggregated price feed that has many single liquidity contributors who are genuine price originators. I am not sure how many other ways that I can articulate this to get you to understand, but I will try one final time. It is the RE-aggregation of feeds that are already aggregated that I am suggesting is not efficient because it is… Read more »
Talking from the customer side, we only care about execution price and stability of platform/price feeds (which are actually executable). Given what happened on Jan 15th with the EURCHF. the debate about POP vs multiple liquidity providers should be a hotter topic. Take IG Group for example who boast 11+ tier one investment bank providers. They had the worst executions. This highlights the fact that it is not just good enough having access to as many liquidity providers as possible….but to have strong relationships with the providers you have. If you are a pure mkt maker (which I thought IG… Read more »
